  The tables, intended for use with The Nautical Almanac, are designed for precise interpolation of altitude for declination by means of interpolation tables which facilitate linear interpolation and provide additionally for the effect of second differences when : CreateSpace Publishing. I purchased the Nautical Almanac because the book uses a Almanac for all it's problems and the real Almanac is easier to use than the tables in the book. Some of the tables in the book (One Hu8ndred Problems) are missing. The Almanac is full sized and easier to read/5(11).

  In the Nautical Almanac, the permanent table for increments also includes corrections for v, the difference between the actual change of GHA in one hour and a constant value used in the interpolation tables; and d, the change in declination in one hour. In the Nautical Almanac, v is always positive unless a negative sign (−) is shown. This. Supplemental Material» Determining Hc and Zn Using the Publications» Interpolation is Required to Use The Nautical Almanac. This sounds easy, and it is. However, both books involve tables, and therefore we must interpolate between table entries. For example, The Nautical Almanac gives the position of the Sun every hour throughout the year.

The National Imagery and Mapping Agency is responsible for the compilation of these tables. The Nautical Almanac Office of the U.S. Naval Observatory and H. M. Nautical Almanac Office have cooperated in their design and preparation. The tables are published in the United Kingdom as A.P. , Sight Reduction Tables for Air Navigation.
